New federal energy requirements for fractional horsepower motors have required that the S02E2A motor be replaced with a more energy efficient model. The S02E2A is no longer in production and has been replaced by the C02E2A.

While the C02E2A uses less amps, it is a physically larger motor and will require modifications to any fans that originally used the S02E2A. Directions for making the required modifications can be found below.
